A techniques for improved guiding of hyper-redundant manipulator probes into a constrained space which make use of the known characteristics of the space into which the probe is being inserted to increase the efficiency of the computation of the path of the probe. Embodiments of the invention achieve this through an optimisation function which determined a new orientation which minimises the deviation between each of: a) the point on the probe where the probe starts to follow a defined curve within the constrained space and a predetermined initial point, and b) the distal end of the probe and said defined curve.

Probe guiding

Methods of controlling a hyper redundant manipulator, the hyper redundant manipulator including: a plurality of sections comprising a first free end section and a second end section; and a base arranged to receive the plurality of sections in a coiled configuration, the base being coupled to the second end section of the plurality of sections, the method comprising: receiving a trajectory for movement of the plurality of sections; determining an error in position and/or orientation relative to the trajectory for one or more sections of the plurality of sections, the error being caused at least in part by the coiled configuration; and controlling movement of the one or more sections using the determined error to compensate for the error in position and/or orientation of the one or more sections.
